Washington -LRB- CNN -RRB- -- Only a third of U.S. voters think that most members of Congress deserve to be re-elected this year , according to a new national poll . That 's the lowest number ever recorded for that question in a CNN survey .

The CNN/Opinion Research Corp. poll , released Tuesday , indicates that only 34 percent feel that current federal lawmakers deserve re-election , with 63 percent saying no .

According to the survey , 51 percent feel their own member of Congress should be re-elected -- also an all-time low in CNN polling -- while 44 percent say their representative does n't deserve to be returned to office in November .

The numbers on both questions are even lower than in 1994 , when an anti-incumbent fever helped Republicans win back control of both the House and the Senate from Democrats . The trend line on those questions goes back to 1991 , when they were first asked .

`` This is not a good year to be an incumbent , regardless of which party you belong to , '' said CNN polling director Keating Holland . `` Voters seem equally angry at both Republicans and Democrats this year . ''

Fifty-six percent of people questioned in the survey say that most Democrats in Congress do not deserve to be re-elected . An equal percentage say that most congressional Republicans do n't deserve re-election .

The poll suggests Americans are split when it comes to their vote this November , with 47 percent of registered voters saying they will support the Republican candidate in their district for the House of Representatives and 45 percent saying they will back the Democrat . Republicans trailed the Democrats by 6 points in November .

The voters ' cool view of incumbents of both parties `` may hurt the Democrats more because there are more Democratic incumbents , '' Holland said . `` It 's a change from 2006 , when voters concentrated their anger at GOP members of Congress . ''

The generic ballot question asked respondents if they would vote for a Democrat or Republican in their congressional district , without naming any specific candidates .

The Democrats currently hold a 255-178 advantage in the House , with two vacant seats that the Democrats once held . Republicans need to win 40 seats to take back control of the chamber .

While President Obama is not up for re-election this November , he will be in 2012 , if he decides to run for a second term . According to the poll , 44 percent of registered voters say Obama deserves re-election , with 52 percent saying the president does not deserve a second term in office . The survey also indicates that 49 percent of Americans approve of the job Obama 's doing as president , with half of the public disapproving of his job in the White House .

`` One problem Obama faces may be the perception that Obama is not a middle-class kind of guy , '' Holland said . `` Only 4 percent of Americans describe themselves as upper class . But a 45 percent plurality say that Obama belongs to the upper class , with 42 percent saying he is from the middle class and 12 percent describing him as working class . ''

The CNN/Opinion Research Corp. poll was conducted Friday through Monday , with 1,023 adult Americans , including 954 registered voters , questioned by telephone . The survey 's sampling error is plus or minus 3 percentage points both for all Americans and for registered voters .
